A head assembly for a borehole extensometer and an improved extensometer for measuring subsurface subsidence. A plurality of inflatable anchors provide discrete measurement points. A metering rod is fixed to each of the anchors which are displaced when subsidence occurs, thereby translating the attached rod. The head assembly includes a sprocket wheel rotatably mounted on a standpipe and engaged by a chain which is connected at one end to the metering rod and at the other end to a counterweight. A second sprocket wheel connected to the standpipe also engages the chain and drives a connected potentiometer. The head assembly converts the linear displacement of the metering rod to the rotary motion of the second sprocket wheel, which is measured by the potentiometer, producing a continuous electrical output.

The present invention relates to a metal-oxide ceramic composition useful in induction heating applications for treating uranium and uranium alloys. The ceramic composition is electrically conductive at room temperature and is nonreactive with molten uranium. The composition is prepared from a particulate admixture of 20 to 50 vol. % niobium and zirconium oxide which may be stabilized with an addition of a further oxide such as magnesium oxide, calcium oxide, or yttria. The composition is prepared by blending the powders, pressing or casting the blend into the desired product configuration, and then sintering the casting or compact in an inert atmosphere. In the casting operation, calcium aluminate is preferably added to the admixture in place of a like quantity of zirconia for providing a cement to help maintain the integrity of the sintered product.

Patent for a combination tool. Illustration included.

Patent for an apparatus for extracting honey. Illustration included.

Patent for improved casing water-packer used for Artesian wells.

Patent for "an improved check-row attachment for corn-planting machines, the object of my invention being to provide an efficient mechanism for actuating the seed-dropping mechanism of the corn-planter and which my be operated by the feet of the driver or by a check-wire in such manner as to cause the seeds to be planted in check-rows." (lines 8-15) including illustrations.

Patent for cigar case. Illustration included.

Patent for a churn dasher. Illustration included.

Patent for a new and improved car-axle box. This design consists "[i]n an axle-box, the combination, with the box having the wedge-shaped projections and slots, of the cover having pins and wedge-shaped recesses formed between said pins and the top of the lid, whereby the gravity of the cover will wedge it to the box when the pins are without a bearing" (lines 52-58).

Patent for an improved design of automatic air brakes for use in railway cars.

Patent for bale ties that "have the securing members permanently connected" (lines 12-13) and do not have projecting ends that could damage cotton bales or other fibrous materials.

Patent for a new boring tool used for digging post holes, shallow wells, and for like purposes. It has a pilot bit and a cutting disk that carries the loosened dirt from the bore to the surface.

Patent for an improved boll-cotton gin which gathers the cotton bolls without crushing them or intermingling the product with impurities by separating the seed cotton from the bolls and hulls.

Patent relating to nanoscale technology based mixed-signal system design.

Patent for an improved bottle for the purposes of carefully applying disinfecting fluid. The patent describes and illustrates a bottle that can be sold as-is, with an apparatus that releases the liquid drop by drop to prevent waste.

Patent for improved gear structures for motor vehicles that pull plows or other items across the ground or across roadways.

Patent for improvements on traction-engines to make steering easier especially around short curves, and to decrease the amount of "dead weight" (line 21) of the machine overall.

Patent for a new turnstile design for use in train cars, "especially adapted for use in so called " pay-as-you-enter " cars." (lines 11-12) including instructions and illustrations.

Patent for useful improvements to the valve mechanism for steam engines. The invention allows an improved means for actuating the slide valve without the use of eccentrics. The valve can also be operated into closed positions at various degrees, and also to reverse the direction of travel of the valve.

Patent for a wire fence building implement. This implement is "adapted to take up slack in an unbroken fence-wire, draw together ends of a broken fence-wire, so as to permit said ends to be spliced together, cut off surplus wire, and pull staples from the fence-posts" (lines 9-15). Illustrations included.

Patent for a "latch of strong and durable construction, designed principally for use in connection with the end gate fastener."

Patent for a variable speed mechanism. Illustration included.

Patent for a tying mechanism for harvesters. Illustration included.

Patent for improved wheel system which provides traction over a variety of surfaces.
